ABSTRACT
Accidents and incidents often occur, because a basic and seemingly simple rule is 'forgotten', either unintentionally (error, lapse) or with some degree of deliberate negligence (violation). The present experiment examined the utility of a rehearsal and a last-minute reminder in reducing the magnitude of deviations from an important safety rule by qualified, but relatively inexperienced pilots, specifically, remaining above an altitude of 500-ft. A single rehearsal flight entailing a search for a target on the ground increased the minimum altitude in later flights, but this positive effect did not completely generalize when the target on the ground was changed. These results suggest that the rehearsal flight was encoded in a context-specific manner. The addition of an explicit, last minute reminder about the mandated minimum altitude just before each test flight failed to significantly alter the pilots' behavior. The results are discussed with respect to their theoretical and practical implications.
